Which group of babies is more likely to die from SIDS and why?

The group of babies that is identified as being more likely to die from Sudden Infant Death Syndrome (SIDS) is African American babies, particularly because they are more often placed on their stomachs to sleep. The practice of putting infants to sleep on their stomachs has been recognized as a significant risk factor for SIDS. Research indicates that sleeping on the back is the safest position and greatly reduces the risk of SIDS. Cultural practices and parental education around sleep positioning can influence these rates, leading to greater vulnerability in certain demographics.

Other options mentioned do touch upon relevant topics, but they don't directly address the primary risk factors associated with SIDS. For instance, access to healthcare can play a role in overall infant health, yet it does not specifically correlate with SIDS risk as much as sleep positioning does. Similarly, environmental factors can impact various aspects of health and well-being, but the direct link to SIDS is less clear. Cultural practices could also influence infant care, but the increased risk from sleep positioning is a more recognized contributing factor in this context.
